Regarding DTE or DCE type of UART communication in KEA128 !

[jashanm]

Hi,

      I am working on  KEA 128 micro-controller, i want to know what type  of end instrument that converts user information into signals or reconverts received signals is used in UART communication (DTE or DCE) in KEA128. Since am working with a DCE system i need to know this, which i dint get in the data sheet of KEA128  ????

Hi Jashan,

In the KEA128, the kind of UART module is the TTL Serial.

So it needs you to use the TTL-232 converter to connect the UART module as the DTE to the DCE.

Hope it helps.
Have a great day,

It doesn't specify whether it's DCE or DTE, because it depends on how you design the hardware and software.  The UART is capable of doing either.  The DTE/DCE terminology usually refers to RS-232 hardware, because the TX pin on the DTE end has to go to the RX pin on the DCE end.
